Tony, I will help you out, and we will post the final .bat here for reference for other people. Rest will be through PM to not clutter the forum. Also fixed the initial posts' images. Sorry for not responding earlier, never got the notifications. Changed my email address now, this one gets them. Probably a spam issue.
Note there's still no improvements in RatRefresh. However, I'm going to do a new version with better usability and hopefully detection of the display device. However, the main issue will still be there, which is restarting of the display driver. So far I've been unable to find a solution, or any third-party tool that can apply new EDID overrides without restarting the video driver.
Again, please prove me wrong :-)
